I need to sum of grid column. but I don't know how to get all the rows even not selected one.
For only selected I do,
(controller)
var sum =0;
var grid = this.getMyGrid().getSelectionModel.getSelection();
Ext.each(grid,function(item)){
sum += item.data.qty;
}
but How should I do to get grid data that include not selected row too?
Thank you!
this.myGrid().store.each(function() {
...
})

I have an ag-grid table with 2 columns - one text and one number.
I need to add a custom row to the top of my ag-grid table with the total value of the number column and the word "ALL" in the text column.
This needs to be on the top. And should not change its position even if the table is sorted.
Also, the row should be selectable.
Any help in this regard will be highly appreciated!
Sounds like you are describing Row Pinning which is already a feature in AG Grid. However, since you've also stated that row selection is a requirement, this will not be possible with Row Pinning as it's not supported.
Instead what I'd recommend is adding an extra row object inside the rowData for the custom row, and handling the update of the number column and the custom row position yourself when necessary:
If you want to handle the total value of the number column then you can use the following logic:
function updateTotalRowNode() {
let totalRowNode;
let sum = 0;
gridOptions.api.forEachNode((node) => {
if (node.data.totalRow) {
totalRowNode = node;
} else {
sum += node.data.gold;
}
});
totalRowNode.setDataValue('gold', sum);
}
If you want to keep the custom row always on the top row then you can implement the postSort callback:
postSort: (rowNodes) => {
// here we put All row on top while preserving the sort order
let nextInsertPos = 0;
for (let i = 0; i < rowNodes.length; i++) {
const athlete = rowNodes[i].data.athlete;
if (athlete === 'All') {
rowNodes.splice(nextInsertPos, 0, rowNodes.splice(i, 1)[0]);
nextInsertPos++;
}
}
},
See the following plunker for the implementation.
I'm trying to recreate the following pivot table with ag-Grid:
Using floatingBottomRowData I can't find a way to pass the values for all generated columns. so one pair of values is getting duplicated:
My goal is to access the column group value for each cell of the floating row.
Right now I can't tell the difference between column groups (resulting in duplicated values).
Is there any way to differentiate the different (col1, col2) pairs?
The answer that was given in the ag-grid forum is:
to get the pivot key, do this:
floatingCellRenderer: function(params) {
if (gridOptions.columnApi.isPivotMode()) {
console.log(params.column.getId());
var parent = params.column.getParent();
if (parent) {
var pivotKey = console.log(parent.getOriginalColumnGroup().getColGroupDef().pivotKeys[0]);
}
}
}
to get the columns in the active pivot, use the column API, eg columnApi.getPivotColumns(), which will return a list of the pivot columns. this will be in order, so if you have many columns, there will be one for each parent you traverse.
What I did for the pivot_ type of pinned row: I added a custom pinned row renderer to my column, where I expect the aggregated function to show (for me it was for sum and avg). If I change the pivot function I called a refresh on the pinned row to set the new values.
pinnedRowCellRenderer: function (render)
{
for (var obj_id in render.data)
{
if (obj_id == render.column.colId)
{
return '<div>' + render.data[obj_id] + '</div>';
}
}
return '<div></div>';
}
And the result looks like this:

Hope it helps!
I want to sort the columns in my grid, just like the rows. I have made a simple sort function that is called from an actioncolumn handler:
sortColumns:function(record) { // The record after which's values the columns are ordered
var columns = this.columns;
Ext.Array.sort(columns,function(col1,col2) {
if(record.get(col1.dataIndex) > record.get(col2.dataIndex)) return 1;
if(record.get(col1.dataIndex) < record.get(col2.dataIndex)) return -1;
if(col1.dataIndex > col2.dataIndex) return 1;
if(col1.dataIndex < col2.dataIndex) return 1;
throw new Error("Comparing column with itself shouldn't happen.");
});
this.setColumns(columns);
});
The setColumns line now throws the error
Cannot add destroyed item 'gridcolumn-1595' to Container 'headercontainer-1598'
which is because the "old" columns are destroyed first, and then the "new" columns, which are the same and thus destroyed, are applied.
I only want to change the order, but I didn't find any function to do it. Do you know how to do it?
Drag-drop ordering of the columns works, so it is doable; but I don't find the source code where sencha did implement that drag-drop thingy. Do you know where to look for that code?
Reconfigure method needs two arguments
grid.reconfigure(store, columns)
Here is the fiddle that changes the columns programatically https://fiddle.sencha.com/#fiddle/17bk
I have found that columns are items of the grid's headerCt, so the following works well, and unlike the other answers, it does not create new column components, keeping the column state and everything:
var headerCt = normalGrid.headerCt,
columns = headerCt.items.getRange();
Ext.Array.sort(columns,function(col1,col2) {
if(record.get(col1.dataIndex) < record.get(col2.dataIndex)) return -1;
if(record.get(col1.dataIndex) > record.get(col2.dataIndex)) return 1;
if(col1.dataIndex < col2.dataIndex) return -1;
if(col1.dataIndex > col2.dataIndex) return 1;
return 0;
});
headerCt.suspendLayouts();
for(var i=0;i<columns.length;i++)
{
headerCt.moveAfter(columns[i],(columns[i-1] || null));
}
headerCt.resumeLayouts(true);
There is a reconfigure method which can be used to achieve reordering, e.g:
grid.reconfigure(columns);
Check the this.
I couldn't manage to do it without storing columns in a custom field and using reconfigure, maybe someone can suggest something better (reconfigure doesn't work well with just regular columns field it seems):
Ext.define('MyGrid', {
extend: 'Ext.grid.Panel',
//just renamed "columns"
myColumnConfigs: [
//all your column configs
]
});
//to rearrange inside controller, also need to call it on grid render
var grid = this.getView();
var columns = grid.myColumnConfigs;
//...do your sorting on columns array
grid.reconfigure(columns);
I want to add custom row as 1st row in grid.Supose in this link

I want to insert custom hardcorded value as first row in this grid .How to do this i dont want to do it with store.Bascially i want to add div after header and populate my string into that
Thanks
grid.getStore().insert( index, records ) will do this if you set index = 0
you can use this code:
var grid = Ext.getCmp("yourGridId").getStore()
var myArray=new Array()
myArray['id'] = '1';
myArray['value'] = 'Dummy';
var rec = new Ext.data.Record(myArray);
grid.insert(0, rec);
I have a grid within a form as in the attached image. When the the customer name is changed, then the grid store is loaded with records corresponding to the customer. I want the balance textfield to be populated with the sum of Amount due column.
The image is here.
Use like this:
store.load({
scope : this,
callback: function(records, operation, success) {
//here the store has been loaded so you can use what functions you like.
//This code sum numbers in certain column
sum = 0;
store.each(function (rec) { sum += rec.get('NameColumn'); });
}
});
Use the store summary function:
var sum = grid.getStore().sum('NameColumn');
